Let's start with the bad: if you're hoping to use this on macOS while leaving HDR enabled then please don't buy it.
On macOS the brightness of SDR content (UI/desktop) is set extremely low and unadjustable (100nits it seems), which makes it unusable for office/productivity use unless you're in a pitch dark room (and even then the brightness is still rather low). Effectively your only choices on macOS to have HDR enabled all the time are to use either the MacBookPro 14/16" with XDR display, or the very affordable $5-6 Apple XDR display (plus the lovely $1K stand, + tax).
On Windows you can control SDR brightness relative to HDR content; UI's color/contrast will be as usual (with HDR monitors) a bit washed out but you can 'fix' that further using your graphics's card settings.
It is however gorgeous for viewing HDR videos, gaming in HDR.
The picture quality is fantastic in SDR mode, but at that point the difference with an IPS 4K screen that costs a fraction of its price is not that drastic in a normally lit room. Compared to my Dell U2720Q the black are indeed black on the LG OLED but you really notice the difference in a darkly lit or pitch black room (at that point the typical IPS glow of the Dell panel makes black grey-ish looking).
Build quality for the ports at the back of the screen is questionable; it feels like the ports are going to bend/fall off every time you plug something into them.
